Check the seat height using the following simple procedure. Use shoes with a flat sole for this check:
· Pull out the upper seatpost until the pin engages in the hole and close the quick release.
· Sit on the saddle and put your heel on the pedal, so that it moves to its lowest position. In this position the leg should be
fully extended. Note that the hips should stay straight and level. To adjust the seat height, you need to undo the quick-
release of the segment clamp (please read page 17 first).
· Do not pull the seatpost out beyond the marking on the tube surface.
· The loosened seatpost can now be adjusted for height. Make sure that the seatpost isn’t greased. If it doesn’t slide smoothly
in the frame, clean out and remove all grease from inside the frame and on the seatpost. If you have further problems,
consult your dealer. In no event use force to move the seatpost.
· Set the saddle straight, by lining up the saddle nose either with the bottom bracket or the main frame tube.
· Re-fasten the quick-release.
· Check that the seatpost is securely fixed by grasping the front and rear of the saddle and attempting to twist it. If it doesn’t
move at all, it’s secure.
· Does the leg extension seem correct when you repeat the test? Check it by moving your foot to the ideal pedalling position,
with the ball of the foot above the pedal axle. The knee should now be slightly bent – if this is so, you’ve reached the correct
saddle height.
· Check that you can stay in the saddle and still reach the ground with your tiptoes. If this isn’t the case, put the saddle a
little lower.
· Remember the scale at the seatpost. After unfolding the Frog later on, you immediately know the correct position.

Danger
: Do not ride if the seatpost is withdrawn beyond the ‘MINIMUM INSERTION’ mark! The Frog seatpost is not designed for
the assembly of carriers or panier bags. This could lead to overload and failure of the seatpost.
Adjusting the handlebars
You can adjust the height of the handlebar stem by undoing the quick-release and pushing the pin.
· Check that everything is secure on the stem, by holding the front wheel between your legs and attempting to twist the
handlebars with your hands. If it doesn’t turn, it’s secure.
Danger
: Do not ride if the quick release of the handlebar stem is not closed or if the pin did not engagein one of the holes. Never
undo the quick release during riding the bike.
Adjusting reach and setting the saddle angle
The distance between the handlebar grips and the saddle (reach), and the angle of the saddle, are important factors when it
comes to how much you’re leaning forwards, and hence for your riding comfort and performance.
The reach can be adjusted over a short distance using the saddle rails, by sliding the saddle forwards or back on the seatpost
clamp. This will also affect pedalling: if the saddle is right back, you’ll be pedalling more ‘from behind’, and vice versa.
The geometry of the Frog was designed so that for normal use, the saddle is positioned as far forwards as possible. This
minimises folded size.
The saddle should in general be set dead level.
· Undo both seatpost clamp bolts, turning each of them at most two or three turns anticlockwise. No more, or the whole
assembly can fall apart.
· Move the saddle forwards or backwards as required. Often a sharp slap to the saddle is needed. Re-tighten the bolts, turning
them clockwise.
· Depending on which of the bolts is done up first, the saddle angle may change. Observe the recommended tightening torque
of 9-12 Nm for the bolts.

· When you’ve tightened everything, check whether the saddle tilts, by pushing alternately on the front and back.
Danger
: When you change saddles, check that the saddle rails are designed for a 7mm clamp. Other types of saddle rail may
cause failure of the seat clamp and a nasty accident.
Adjusting the reach of the brake levers
The distance between brake levers and handlebar grips is adjustable. The levers can be brought closer to the bars, making them
easier to use for riders with small hands. The lever position where the brakes start to ‘bite’ also needs to be adjusted for finger
length.
